    Propagates all row update, insert, and delete changes to the
underlying data source backing this CachedRowSetImpl
object.

NoteIn the reference implementation an optimistic concurrency implementation
is provided as a sample implementation of a the SyncProvider
abstract class.

This method fails if any of the updates cannot be propagated back
to the data source.  When it fails, the caller can assume that
none of the updates are reflected in the data source.
When an exception is thrown, the current row
is set to the first "updated" row that resulted in an exception
unless the row that caused the exception is a "deleted" row.
In that case, when deleted rows are not shown, which is usually true,
the current row is not affected.

If no SyncProvider is configured, the reference implementation
leverages the RIOptimisticProvider available which provides the
default and reference synchronization capabilities for disconnected
RowSets.
Throws: SQLException – if the cursor is on the insert row or the underlying
         reference synchronization provider fails to commit the updates
         to the datasource
SyncProviderException – if an internal error occurs within the

    Retrieves the name of the SQL cursor used by this
CachedRowSetImpl object.
In SQL, a result table is retrieved through a cursor that is
named. The current row of a ResultSet can be updated or deleted
using a positioned update/delete statement that references the
cursor name. To ensure that the cursor has the proper isolation
level to support an update operation, the cursor's SELECT
statement should be of the form select for update.
If the for update clause
is omitted, positioned updates may fail.
JDBC supports this SQL feature by providing the name of the
SQL cursor used by a ResultSet object. The current row
of a result set is also the current row of this SQL cursor.
Note: If positioned updates are not supported, an
SQLException is thrown.
Throws: SQLException – if an error occurs

    Retrieves a ResultSetMetaData object instance that
contains information about the CachedRowSet object.
However, applications should cast the returned object to a
RowSetMetaData interface implementation. In the

    Retrieves the value of the designated column in the current row
of this CachedRowSetImpl object as an
Object value.

Java object type corresponding to the column's SQL type,

behavior so that it gets the attributes of an SQL structured type
as an array of Object values.  This method also custom
maps SQL user-defined types to classes in the Java programming language.

If the number is positive, the cursor moves to an absolute row with
respect to the beginning of the rowset.  The first row is row 1, the second

to the fourth row, starting from the beginning of the rowset.

If the number is negative, the cursor moves to an absolute row position
with respect to the end of the rowset.  For example, calling
absolute(-1) positions the cursor on the last row,
absolute(-2) moves it on the next-to-last row, and so on.
If the CachedRowSetImpl object crs has five rows,
the following command moves the cursor to the fourth-to-last row, which

    Moves the cursor the specified number of rows from the current
position, with a positive number moving it forward and a
negative number moving it backward.

If the number is positive, the cursor moves the specified number of
rows toward the end of the rowset, starting at the current row.
For example, the following command, in which
crs is a CachedRowSetImpl object with 100 rows,
moves the cursor forward four rows from the current row.  If the
current row is 50, the cursor would move to row 54.

   crs.relative(4);
 

If the number is negative, the cursor moves back toward the beginning
the specified number of rows, starting at the current row.
For example, calling the method
absolute(-1) positions the cursor on the last row,

will move to the position after the last row. If the number specified
would move the cursor one or more rows before the first row, the cursor
moves to the position before the first row. In both cases, this method
throws an SQLException.

Note: Calling absolute(1) is the same as calling the

    public boolean relative(int rows) throws SQLException {

    Moves this CachedRowSetImpl object's cursor to the
previous row and returns true if the cursor is on
a valid row or false if it is not.
This method also notifies all listeners registered with this
CachedRowSetImpl object that its cursor has moved.

Note: calling the method previous() is not the same
as calling the method relative(-1).  This is true
because it is possible to call previous() from the insert
row, from after the last row, or from the current row, whereas
relative may only be called from the current row.

The method previous may used in a while
loop to iterate through a rowset starting after the last row
and moving toward the beginning. The loop ends when previous
returns false, meaning that there are no more rows.
For example, the following code fragment retrieves all the data in
the CachedRowSetImpl object crs, which has
three columns.  Note that the cursor must initially be positioned
after the last row so that the first call to the method
previous places the cursor on the last line.
